Abstract:
In one embodiment, a method is provided. A first root node of a first Multipoint-to-Multipoint (MP2MP) Multi-Protocol Label Switching (MPLS) tree, advertises to a second root node of a second MP2MP MPLS tree a first label for the second root node to use to send multicast traffic to the first MP2MP MPLS tree. The first root node receives a second label from the second root node for the first root node to use to send multicast traffic to the second MP2MP MPLS tree. Communications are carried out between the first MP2MP MPLS tree and the second MP2MP MPLS tree using the first label and the second label. In another embodiment, apparatus are also provided.
